A high-speed train in Japan travels a distance of 300. kilometers in 3.60 x 103 seconds. What is the average speed of this train? (Turn the time into hours by using a unit conversion)

Answer 1

370.8 seconds = 6.18 minutes = 0.103 hours = about 1/10 of an hour

300 km in 1/10 of an hour is 3000 km in one hour

3000km/hr = about 1864 mph

one km = 0.6214 miles

3000 x .6214 = 1864

Answer 2

Given Information

1. 300 kilometers= distance
2. 3.60* 10³ seconds = time

To Convert Seconds to hours

1. We will be using dimensional analysis

3.60 *10³ seconds × 1 minute × 1 hour = 1 hour

60 sec 60 min

To Calculate Speed

1. To calculate the speed we will use the formula distance= (x= speed) ÷ time
2. 300 kilometers= (x kilometers/ second) / (1 hour)
3. Speed= 300 kilometers/ hour
